Bangladesh   Medical facilities in Bangladesh are very poor. Make sure your insurance covers both medical treatment, including medical evacuation to the UK, and unexpected losses/expenses.       Check Foreign and Commonwealth Office Travel Advice before you leave home.       British passport holders must hold a valid visa for entry to Bangladesh. Although this can be obtained on arrival, visitors can encounter problems and are advised to obtain a visa before travelling. Visitors should check with the Bangladeshi High Commission in London before travelling that they have been issued with the correct visa.       Extensions to your visa can be obtained from the Department of Immigration & Passports. Failure to do so could result in a hefty fine.       Ensure that you have enough funds for your stay and return flight. Bank transfers can take time. Major credit cards are accepted in many restaurants in Dhaka and by well-established travel agencies. Acceptance of credit cards cannot be guaranteed in more remote areas.       Keep all your personal belongings, particularly your passport and money, in a safe place at all times. Pickpockets and bag snatchers are commonplace in Bangladesh.       Always respect local laws and customs. Bangladesh is a predominantly Muslim country. Dress appropriately in public. If in doubt, take local advice.       Malarial and dengue fever mosquitoes are found in Bangladesh and you should seek medical advice before travelling. Many foreigners fall victim to the heat and to diarrhoea and similar illnesses caused by eating and drinking contaminated food and drink. Only eat recently prepared food which has been thoroughly cooked, and drink plenty of bottled water, or bottled drinks, to prevent dehydration.       Leave a photocopy of your passport and your travel itinerary with a relative or friend in the UK.       Enter next of kin details into the back of your passport.       Never carry drugs. There are several penalties in Bangladesh for drug offences.
